ERCOT's 454 GW Generation Queue Locks 24–36 Month Energization Timeline into New-Build Site Economics

## The number

ERCOT's generation interconnection queue now holds 454 GW of requested capacity—40% of all queued generation across US ISOs. Queue depth at this scale translates directly to multi-year energization timelines: new large loads entering the ERCOT footprint should price 24–36 months of delay into every site decision and capex model.

## What it means for build decisions

A hyperscale tenant evaluating a greenfield ERCOT site today faces not only land, construction, and utility-interconnection costs but also the opportunity cost of deferred revenue during a two-to-three-year power wait. That delay changes the IRR on the entire facility. Developers selling into ERCOT markets must now demonstrate how they are mitigating queue risk—either through pre-secured generation offtake, behind-the-meter solutions, or staging the build to match realistic energization dates.

For markets outside ERCOT with shallower queues, the contrast is sharp. SPP's Oklahoma City and Tulsa markets, both posting 75.3/100 Excess Power scores on DCPI this week, carry queue depths measured in months, not years. The same hyperscale load that waits 30 months in ERCOT could energize in 12–18 months in SPP—a gap that compounds across every quarter of delayed cash flow.

## The portfolio implication

Capacity planners with multi-ISO portfolios should now model ERCOT sites as longer-fuse assets. Queue depth this deep does not reverse in one interconnection-study cycle. It signals sustained pressure and requires a different risk profile than markets where generation supply is pacing load growth. The decision is not whether to build in ERCOT—it is when to start, and what to build in parallel where power is available now.
